Overview of this book

Developers have changed their deployment artifacts from application binaries to container images, and they now need to build container-based applications as containers are part of their new development workflow. This Docker book is designed to help you learn about the management and administrative tasks of the Containers as a Service (CaaS) platform. The book starts by getting you up and running with the key concepts of containers and microservices. You'll then cover different orchestration strategies and environments, along with exploring the Docker Enterprise platform. As you advance, the book will show you how to deploy secure, production-ready, container-based applications in Docker Enterprise environments. Later, you'll delve into each Docker Enterprise component and learn all about CaaS management. Throughout the book, you'll encounter important exam-specific topics, along with sample questions and detailed answers that will help you prepare effectively for the exam. By the end of this Docker containers book, you'll have learned how to efficiently deploy and manage container-based environments in production, and you will have the skills and knowledge you need to pass the DCA exam.

We will also use docker-compose files for deploying Swarm orchestrated applications with their components distributed on different hosts, but that requires a cluster running. In that case, we will not use the docker-compose binary to deploy the application; only the definition file will be valid and we will use it with the docker stack action. In Docker Swarm, we deploy swarm services, not containers.
  2. d: Docker Compose provides all required actions to build, share, and deploy multi-container applications.
  3. a and c: Docker Compose will review whether project images are present in the host. If they are not, the Docker daemon will try to download all not-present ones. Once the Docker daemon has all the required images, it will start all project containers and our terminal will be attached to containers' standard and error output unless the --detach or -d argument is used.
  4. a: Docker Compose will allow us...
